Description

Technical Field

[0001] This application belongs to the technical field of alarm devices, and particularly relates to an active alarm device. Background Technology

[0002] Alarms, as common security devices, are widely used in personal safety scenarios, especially when users encounter dangerous situations. Triggering an alarm quickly draws the attention of those nearby or deters potential threats. Some existing alarms use a pin-type trigger mechanism, meaning the alarm is activated and sounds by pulling out a pin. This design, to some extent, meets the need for rapid alarm triggering and is relatively straightforward to operate.

[0003] However, in practical use, this type of latch-type alarm has certain shortcomings. The latch is usually inserted quite deeply into the housing, which makes it easy to damage the housing when the latch is pulled out. During reinstallation, it is prone to jamming or misalignment, which not only reduces the efficiency of use, but may also damage the latch or the alarm itself. Utility Model Content

[0004] To address at least one of the problems existing in the prior art, an active alarm device with improved durability is provided.

[0005] The active alarm includes a housing, a functional component, and a locking ring. The housing has an inner cavity, a first mounting hole, and a second mounting hole, with the first mounting hole communicating with the inner cavity. The functional component is disposed within the inner cavity and includes a metal part facing the first mounting hole. The locking ring includes a trigger section and a fixing section, the length of which is greater than the length of the fixing section. The trigger section is disposed in the first mounting hole and fitted onto the metal part. The functional component is configured to issue an alarm when the trigger section is separated from the metal part. The fixing section is disposed in the second mounting hole and engages with it.

[0006] In the aforementioned active alarm, the trigger segment is fitted onto the metal part. When the locking ring separates from the metal part, the detection switch is triggered, and the functional components can then issue an alarm. The alarm operation is simple, allowing users to quickly sound the alarm in dangerous situations. The engagement of the fixed segment with the second mounting hole ensures the locking ring is stably installed in the housing, effectively preventing accidental separation due to accidental activation. Because the trigger segment is longer than the fixed segment, it can penetrate deeper into the housing for better fit within the metal part. The fixed segment is relatively shorter than the trigger segment, allowing the engagement position between the trigger segment and the second mounting hole to be positioned adjacent to the opening of the second mounting hole. The fixed segment does not need to be inserted very deeply into the second mounting hole to engage, facilitating the removal and reinstallation of the locking ring and reducing the risk of damage due to excessive elastic deformation of the housing.

[0007] In some embodiments, the active alarm further includes a positioning structure, which includes a first positioning part and a second positioning part. The first positioning part is disposed on the fixed section, and the second positioning part is disposed on the wall of the second mounting hole. The first positioning part and the second positioning part cooperate to allow the locking ring to be detachably plugged into and pulled out of the housing.

[0008] In some embodiments, the first positioning part is a positioning groove, the second positioning part is a positioning block, and the positioning block is located in the positioning groove.

[0009] In some embodiments, the metal part passes through the first mounting hole, with one end located in the inner cavity and the other end located outside the first mounting hole.

[0010] In some embodiments, the functional components further include a circuit board, a speaker, and a mute switch. The circuit board is mounted in the inner cavity, and the metal component is disposed on the circuit board. The speaker is disposed on the circuit board and partially located outside the housing. The mute switch is disposed on the circuit board and communicates with the outside of the housing; the mute switch is electrically connected to the speaker and is used to control the speaker.

[0011] In some embodiments, the functional component further includes an alarm light disposed on the circuit board, which is activated when the trigger segment is separated from the metal component.

[0012] In some embodiments, the functional component further includes a control key, the circuit board is mounted in the inner cavity, the metal part is disposed on the circuit board, and the control key is disposed on the circuit board; the active alarm also includes a button, the button is connected to the housing, one side of which contacts the control key, and the other side protrudes outside the housing.

[0013] In some embodiments, the housing has a slot located within the inner cavity, and the button includes a connecting strip, a locking block, and a pressing block. The connecting strip is located within the inner cavity, with one side contacting the control key and the other side contacting the inner wall of the housing. The locking block is connected to the connecting strip and is located within the slot. The pressing block is positioned on the side of the connecting strip away from the control key, with the side of the pressing block away from the connecting strip protruding outside the housing.

[0014] In some embodiments, the locking ring further includes an arc-shaped segment located outside the housing and curved toward a side away from the housing, one end of the arc-shaped segment being connected to the fixing segment and the other end being connected to the triggering segment.

[0015] In some embodiments, the housing includes a first housing and a second housing arranged symmetrically, the first housing and the second housing being detachably connected.

[0016] Compared with the prior art, the active alarm provided by the embodiments of this application has the following advantages: by setting the locking ring to include a trigger section and a fixing section, the trigger section is longer and is used to cooperate with the metal part, while the fixing section is relatively shorter and is used to cooperate with the second mounting hole, so that the locking ring can be easily pulled out and reinstalled, and the occurrence of damage to the housing can be reduced.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] Please see Figure 1 This application provides an active alarm 100, which allows users to activate in dangerous situations to attract the attention of those around them or deter potential threats. The alarm emitted by the active alarm 100 can be an audible sound, a flashing light, or a combination of both.

[0036] Please see Figure 2 The active alarm 100 includes a housing 10, a functional component 20, and a locking ring 30. The functional component 20 is located within the housing 10, and the locking ring 30 is connected to the housing 10 and cooperates with the functional component 20. When the user pulls out the locking ring 30, the functional component 20 is activated and an alarm is sounded.

[0037] Please see Figures 1 to 3 In some embodiments, the housing 10 is provided with an inner cavity 101, a first mounting hole 102 and a second mounting hole 103, and the first mounting hole 102 communicates with the inner cavity 101 of the housing 10.

[0038] The functional component 20 is disposed in the inner cavity 101, and the functional component 20 includes a metal part 21, which is directly opposite the first mounting hole 102.

[0039] The locking ring 30 includes a trigger section 31 and a fixing section 32. The length of the trigger section 31 is greater than the length of the fixing section 32. The trigger section 31 is disposed in the first mounting hole 102 and sleeved on the metal part 21. The functional component 20 is configured to issue an alarm when the trigger section 31 is separated from the metal part 21. The fixing section 32 is disposed in the second mounting hole 103 and cooperates with the second mounting hole 103.

[0040] The trigger segment 31 is fitted onto the metal part 21. When the locking ring 30 separates from the metal part 21, it triggers the detection switch, and the functional component 20 can then issue an alarm. The alarm operation is simple, allowing the user to quickly issue an alarm in dangerous situations. Through the cooperation of the fixing segment 32 and the second mounting hole 103, the locking ring 30 can be stably installed in the housing 10, effectively preventing the locking ring 30 from separating from the housing 10 due to accidental activation.

[0041] Since the length of the trigger segment 31 is greater than the length of the fixed segment 32, the trigger segment 31 can penetrate deeper into the housing 10 to be fitted into the metal part 21. The fixed segment 32 is shorter than the trigger segment 31, so the mating position between the trigger segment 31 and the second mounting hole 103 can be set at the opening position adjacent to the second mounting hole 103. The fixed segment 32 does not need to be inserted very deep into the second mounting hole 103 to mate with it. This facilitates the removal and reinstallation of the locking ring 30 and reduces the possibility of damage caused by excessive elastic deformation of the housing 10.

[0042] Please see Figure 3 and Figure 4 In some embodiments, the active alarm 100 further includes a positioning structure 40, through which the fixed section 32 engages with the second mounting hole 103. The positioning structure 40 includes a first positioning part 41 and a second positioning part 42. The first positioning part 41 is disposed on the fixed section 32, and the second positioning part 42 is disposed on the hole wall of the second mounting hole 103. The first positioning part 41 and the second positioning part 42 engage to allow the locking ring 30 to be detachably plugged into and pulled out of the housing 10.

[0043] In some embodiments, the first positioning part 41 is a positioning groove, and the second positioning part 42 is a positioning block. The positioning block is located in the positioning groove, thereby realizing the mating connection between the locking ring 30 and the housing 10.

[0044] It should be noted that the structures of the first positioning part 41 and the second positioning part 42 can be interchanged. That is, in other embodiments, the first positioning part 41 can be a positioning block and the second positioning part 42 can be a positioning groove.

[0045] By placing the positioning structure 40 in the fixed section 32 and the second mounting hole 103, compared with the scheme of placing the positioning structure 40 in the trigger section 31 and the first positioning hole, it is easier to pull out and install the locking ring 30, and it can reduce the occurrence of excessive elastic deformation of the housing 10, which could lead to damage to the housing 10.

[0046] Specifically, if the positioning groove is set in the trigger section 31 and the positioning block is set in the first mounting hole 102, the positioning block can be located adjacent to the opening of the first mounting hole 102, or it can be set on the side adjacent to the first mounting hole 102 and close to the inner cavity 101.

[0047] When the positioning block is located at the opening of the adjacent first mounting hole 102, due to the long length of the trigger segment 31, the trigger segment 31 needs to first open the first mounting hole 102, and then the trigger segment 31 needs to slide a long distance before the positioning block can be inserted into the positioning hole. This will increase the difficulty of pulling out or installing the locking ring 30, and increase the time it takes for the first mounting hole 102 to be opened, which may easily cause damage to the housing 10.

[0048] When the positioning block is adjacent to the side of the first mounting hole 102 near the inner cavity 101, the first mounting hole 102 will be stretched open, which will cause the housing 10 to deform more, making it not only more difficult to pull out or install the locking ring 30, but also easy to damage the housing 10.

[0049] Therefore, by setting the positioning structure 40 in the second mounting hole 103 and the shorter fixing section 32, it is easy to pull out and install the locking ring 30, and it is also easy to extend the service life of the housing 10.

[0050] In some embodiments, the second mounting hole 103 is not connected to the inner cavity 101, that is, the second mounting hole 103 has a bottom, which helps to improve the strength of the housing 10 and reduce the occurrence of damage to the housing 10.

[0051] Please see Figure 2 and Figure 3 In some embodiments, the locking ring 30 further includes an arc-shaped segment 33 located outside the housing 10 and curved toward the side away from the housing 10. One end of the arc-shaped segment 33 is connected to the fixed segment 32, and the other end is connected to the trigger segment 31.

[0052] By setting an arc-shaped segment 33 to connect the fixed segment 32 and the trigger segment 31 together, and the arc shape conforms to the shape of the finger, so as to make it easier to pull out the locking ring 30.

[0053] In some embodiments, the metal part 21 has a first mounting hole 102, with one end located in the inner cavity 101 and the other end located outside the first mounting hole 102. Optionally, the metal part 21 is a long strip of metal part 21.

[0054] In some embodiments, the functional component 20 further includes a circuit board 22, a speaker 23, and a mute switch 24. The circuit board 22 is mounted in the inner cavity 101, and a metal component 21 is disposed on the circuit board 22. The speaker 23 is disposed on the circuit board 22, and partially located outside the housing 10. The mute switch 24 is disposed on the circuit board 22 and communicates with the outside of the housing 10. The mute switch 24 is electrically connected to the speaker 23 and is used to control the speaker 23.

[0055] Please see Figure 5 By controlling the mute switch 24, the speaker 23 can be silenced, so that the locking ring 30 can be pulled out without making a sound when performing maintenance or other work, so as to facilitate the maintenance of the active alarm 100.

[0056] In some embodiments, the functional component 20 further includes an alarm light 25 disposed on the circuit board 22, which is activated when the trigger segment 31 is separated from the metal part 21. The functional component 20 can not only emit an alarm sound but also flash the light, thereby making it easier to attract the attention of others.

[0057] Please see Figure 3 In some embodiments, the functional component 20 further includes a control key 26. A circuit board 22 is mounted in the cavity 101, a metal component 21 is disposed on the circuit board 22, and the control key 26 is disposed on the circuit board 22. Different modes can be selected by triggering the control key 26; for example, an alarm light can be activated independently for illumination. For example, the alarm light can be adjusted to emit a flashing red light to transmit an SOS distress signal.

[0058] Please see Figure 3 , Figure 5 and Figure 6 The active alarm 100 also includes a button 50, which is connected to the housing 10, with one side in contact with the control key 26 and the other side protruding outside the housing 10.

[0059] Button 50 is in contact with control key 26. Pressing button 50 can trigger control key 26 to turn on the alarm light separately or make the alarm light flash red.

[0060] In some embodiments, the housing 10 is provided with a slot 104 located in the inner cavity 101. The button 50 includes a connecting strip 51, a locking block 52, and a pressing block 53. The connecting strip 51 is located in the inner cavity 101, and the connecting strip 51 is arc-shaped and can fit against the bottom of the inner cavity 101 of the housing 10. One side of the connecting strip 51 contacts the control key 26, and the other side contacts the inner wall of the housing 10. The locking block 52 is connected to the connecting strip 51 and is located in the slot 104. The pressing block 53 is disposed on the side of the connecting strip 51 away from the control key 26, and the side of the pressing block 53 away from the connecting strip 51 protrudes outside the housing 10.

[0061] Please see Figure 3 In some embodiments, functional component 20 also includes an indicator light 27 for displaying battery power to facilitate timely charging by the user.

[0062] In some embodiments, the housing 10 includes a first housing 11 and a second housing 12 arranged symmetrically, and the first housing 11 and the second housing 12 are detachably connected. The first housing 11 and the second housing 12 enclose an inner cavity 101. The detachable connection of the first housing 11 and the second housing 12 allows for quick disassembly in the event of a malfunction of the active alarm 100. The method of detachable connection between the first housing 11 and the second housing 12 is not limited; it can be a snap-fit ​​connection or a bolt connection.

[0063] In summary, the embodiments of this application provide an active alarm 100. By setting the locking ring 30 to include a trigger section 31 and a fixing section 32, the trigger section 31 is longer and is used to cooperate with the metal part 21, while the fixing section 32 is relatively shorter and is used to cooperate with the second mounting hole 103. This allows the locking ring 30 to be easily pulled out and reinstalled, and reduces the occurrence of damage to the housing 10.
